"The Long and Winding Road" is a ballad written by Paul McCartney (credited to Lennon–McCartney) that originally appeared on the Beatles' album Let It Be. It became the group's 20th and last number-one song in the United States on 13 June 1970, and was the last single released by the quartet while all four remained alive. "The Long and Winding Road" was listed with "For You Blue" as a double-sided hit when the single hit number one on the US Billboard Hot 100 in 1970.

While the released version of the song was very successful, the post-production modifications to the song by producer Phil Spector angered McCartney to the point that when he made his case in court for breaking up the Beatles as a legal entity, McCartney cited the treatment of "The Long and Winding Road" as one of six reasons for doing so. New versions of the song with simpler instrumentation were subsequently released by both the Beatles and McCartney.
